Audi announces a flock of A3 models at 2013 LA Auto Show

Lots of options for the littlest American Audi.

It was no secret that Audi was planning on expanding its A3 lineup, but this is a bit more than expected. Yesterday at the 2013 LA Auto Show, Audi gave us all the details on the upcoming cars, and it's quite a collection.

For starters, the five-door we all know and love is dead; it has been replaced by the new sedan. Late next year, the sedan will get TDI and S3 variants followed by a new Cabriolet. The lineup will be fully fleshed out in early 2015 when the Sportback body returns with the A3 e-tron PHEV.

The base sedan gets its propulsion from either a 1.8-liter or 2.0-liter TFSI turbocharged four-cylinder. Audi claims the 1.8 is good for 170 hp with the 2.0 pumping out 220 hp. The S3 is also powered by a 2.0-liter turbo, but it is tuned to produce 290 hp. The TDI model will be powered by the Volkswagen Group's next generation 2.0-liter turbodiesel. The Sportback e-tron uses a combination of a 1.4-liter gasoline engine and an electric motor. Combined output for the PHEV is 201 hp and 258 lb/ft of torque. Audi's six-speed S tronic automatic transmission is standard across the lineup.

Audi is also touting the fancy new technology it has loaded into the A3, including the industry's first integration of 4G cellular connectivity and an infotainment system that is powered by Nvidia Tegra silicon, the same stuff that powers many Android tablets.

Like every Audi before, you can spec your car with a vast collection of optional extras to drag your price through the stratosphere. Audi has even gone so far as to offer a Bang & Olufsen stereo, just like you can get in the A7 and A8. No word on whether or not you get the swank pop-up dash speakers, and, really, that is the best part.
